New paper on modeling evaporation of suspended droplets

🎉 Congratulations to Edoardo Cipriano on his latest research publication! I’m happy to share this work, published in the International Journal of Heat and Mass Transfer.
The work is a collaborative effort between CRECK Modeling and Prof. Popinet from Sorbonne Université in Paris, and it introduces a robust volume-of-fluid VOF model for simulating the evaporation of suspended droplets under various gravity conditions—essential for applications from combustion to microgravity studies. 🌍🚀

🔗 Open to the community: The framework is available on the open-source Basilisk platform, offering a valuable tool for researchers and engineers.

Abstract

This study introduces a comprehensive numerical model capable of simulating the evaporation of suspended droplets under different gravity conditions. Unlike previous studies, this work provides a detailed description of the multicomponent evaporation process by integrating: (i) interface-resolved evaporation; (ii) suspension by the action of the surface tension force, and (iii) variable physical properties. The model effectively captures complex phenomena such as thermal expansion, natural convective fluxes, and liquid internal recirculation, which cannot be directly resolved using more widespread spherically-symmetric models. Validation against experimental data confirms the model’s accuracy in predicting the droplet evaporation dynamics, and its utility in resolving discrepancies between prior numerical simulations results and experimental data. The model was implemented in the Basilisk framework; both the code and the simulations setups are freely available on the Basilisk sandbox.
